Having a RadGrid in batch mode with Master and Details tables, when you add a new master record, you are not able to add a new detail record until you save the master record.
This feature should be built in the RadGrid.

Not being able to add rows on the client side is a pretty major limitation of batch editing.

Currently this is a limitation into the RadGrid. The detail tables are created only on the server side.
